Manually issue a push component to a work order and show it consumed from the specified subinventory.

This is where the supply type decision becomes real. Show both types in the same work order so the contrast is direct rather than remembered. Backflush failure is the most common shop floor stoppage. It happens when the supply subinventory is empty — and the operator's work order is blocked by something they cannot see. That sentence is the whole reason the failure is demonstrated deliberately. Over-issue against the work definition is a signal — either the BOM is wrong or the process is. Report on…
